The music you hear is free to copy and distribute. Most of these artists want you to mention (credit) them by name if you use/copy their work. Most of them also ask that you Share Alikeand/or Not Use Their Work in Commercial Works (for-profit) and/or Not Make Derivative Works. All of these conditions can be waived by the creator(s) for any purpose, so PLEASE DO contact them.
